There is an Apple support document on how to do this. You don't need to keep a sim in the phone but you need to put one into it to activate it before taking it back out.
Here's the procedure for 3G and 3GS:
You can use any SIM card associated
with the carrier that your device
supports to activate the phone. Simply
place a SIM card from the last ...

The circle indicates that you're on the cellular GPRS data network. The fact that it's visible also means that you don't have a wifi connection:

Yes, it does slow down. It's more and more noticeable as time goes by.
Apple has acknowledged this issue and they are looking into it.
Here are tips to make it run smoother again. (This is just a solution that has worked for many people. This is not Apple's official solution. They are working on a solution.)
1 - Disable spotlight search.
Settings -> ...

It is not compatible.
Bell's new network (shared with Telus) is a 3G HSPA overlay (on top of their existing CDMA network) which the iPhone 2G does not support.

Searching SMS messages was disabled due to battery life and performance concerns for the 3G, you can see this in the iPhone: Which iOS 4 software features does my iPhone support? article on apple.com

iPhone 3G does not support Spotlight search for SMS/MMS messages.

In general, this is probably because one of, or a combination of the following reasons:
1. Outgoing mail server requires authentication
To avoid abuse by spammers, many outgoing mail servers require authentication for relaying messages across the the internet. You should check if the outgoing mail server you are using for this account requires ...

In my personal experience, iOS 4 was only marginally slower than iPhone OS 3, so it really comes down to features.
First, iOS 4 does not allow you to put home screen wallpapers on an iPhone 3G. I don't have experience with multitasking on a jailbroken device, but again iOS does not provide this functionality on the iPhone 3G. However, given the memory and ...

Here's an article (and video) showing off the issues with iOS4 on a 3G: http://www.macrumors.com/2010/07/28/apple-looking-into-reports-of-problems-with-ios-4-on-iphone-3g/
Seems like not only is it extremely sluggish, but battery life is shortened as well.
Apple has confirmed that there is an issue and are looking into it. I would hold off for now and wait ...

4.2.1 is officially the latest supported version for the iPhone 3G, but you can supposedly install iOS 5 on it with this method: http://osxdaily.com/2012/01/19/install-ios-5-on-iphone-3g-with-whited00r-5/
In the video, it shows the Messages app on the homescreen, so that ought to work for you.

The short answer is there is no way to install an app that was created for an iOS newer then the one you are running. You should connect the device to iTunes and see if you can get it updated to the latest 4.x iOS as many games and apps that target the 4 to 8 year old demographics will certainly work on that older OS.
The longer answer (and some related ...

The data being deleted is in reference to the data already stored on the phone (e.g. the sister's contacts). An iPhone can only be synced to one PC at a time, and if you want to setup syncing with this new PC, you will need to delete all of the data on the iPhone.
If your wife wants her sister's contacts, then she shouldn't sync and wipe the data before she ...

I don't think there's any software that can do it without jailbreaking the device.
iPhone Explorer is free software for Mac and PC that allows you to browse many files and folders without jailbreaking. If you do jailbreak it is also supposed to let you get at MS messages, call history, etc.
I've not used with with a jailbroken device, but can attest that ...

I don't know about the yellow alert symbol, but a quick google for "iphone recovery mode utility" revealed RecBoot, which looks like exactly what you're looking for.
Also, Settings > General > Reset > Reset Network Settings should restart your iPhone.

From the iLounge article
Thus far iOS 4.2 appears to perform as
well as iOS 4.1 did under similar
conditions. Performance even on older
devices such as the iPhone 3G is the
same as iOS 4.1 and thus far we
haven’t observed any significant
changes in battery life.

Flash does not run on any version of the iPhone. You can try using a program like Air Video which will live transcode your DiVX files into a format the iPhone will play back using your computer.
As for playing it natively on your iPhone, VLC (Video Lan Client) is working on a native client but it's not available in the App Store yet.

I had the same problem before, when I replaced a cracked iPhone screen for a friend. When a 3GS digitalizer gets in contact with an iPhone 3G LCD they send the wrong signals to the motherboard(through ribbon cable 3) and then the graphic part of the motherboard brokes. So you will probably have to replace the whole motherboard, be more careful when buying ...

Simply turn off voicemail for calls to google voice using the web interface for that google voice number.
If you activated the carrier settings like in the image below - click the instructions to reverse those changes with the carrier. You could also call your carrier for help since it's a feature that has different commands on a per-carrier basis. They ...

You should try accessing the SMS db from the command line. Some explanation is here: How can I export SMS text messages from my iPhone?
If you see old messages, you can find the corrupt one and retrieve them. If the Sqlite dump command doesn't show them, and the size of the DB implies they are not there, it is likely they are gone.
If you can find old ...

This means that the device was unable to get an IP address via DHCP. The router may need to be rebooted itself, or it may not be set up to hand out IP information via DHCP and your iPhone will have to be set up statically. Check with the administrator of that wifi network for exact details. If it's your own, double check DHCP is enabled for your router, and ...

This is by design, although the basic internal features and functions of iOS4 are present (this is mainly the stuff that apps will use, so you can be sure that if your app says it needs OS4, then you can run it) not all the OS functions are present, and this includes the background switching functionality as well as a few other things. I can't remember them ...

You could attempt to put the iPhone in DFU Mode, and see if you can restore from iTunes. But this is almost certainly a hardware problem, and will require a trip to an Apple Store or a service provider.
To try DFU mode (note that this does a complete wipe, you'll have to rely on whatever backups you made previously):
Plug the phone into your computer.

The final iOS rev for iPhone 3G is 4.2.1, and you could always save a backup before upgrading and restor to the 3.X version if 4.2.1 was too much of a hog.
Hope this helps!
Edit: This thread says its not even worth it. 4.2.1 is crippling to the device.

Apparently doing a hard reset a couple of times in a row can improve the performance:

I'm using the same cables across all my Apple devices (I have so many around, and can't really tell them apart any more). One bit of caution regarding the wall plug, though: there was one model that shipped with either the original iPhone or the 3G which was recalled because it was prone to overheating.
If you haven't run into a problem with yours by now, ...

iOS is always being optimized, and Apple's OS's are known for running faster than previous versions, even on older hardware. iOS 4.0 was bad on the 3G, but 4.1 is much better.
As a rule of thumb, you're always best running the latest version of iOS, unless you're a jailbreaker and/or unlocker, in which case you should run the latest exploitable version of ...
