Nomenclature The terms 2G, 3G and 4G do not refer to a specific wireless standard, but a a whole bunch of different standards: There has been controversy on what standards should be referred to as 4G. When Apple introduced the iPhone 4S, they followed other companies in referring to HSDPA as a 4G standard. HSPA+ is the successor to HSDPA. DC-HSPA+ ...

It means that you are connected on HSPA+. It's actually a 3G technology, and unfortunately, you probably won't experience any speed increase in downloading or surfing. The 4G technology for the "new iPad" is LTE, and is much faster than the existing 3G band. 4G iPhone On AT&T? New Network Indicator Causes Controversy

If you still want to be downloading stuff, then probably yes, switching off 3G probably won't save you much power / battery life. However, when my battery is running low, switching off 3G can make the difference between the battery making it until I get to a charger or not. Obviously in those conditions I stop surfing or doing anything data-related as well, ...

If you see a 3G at the top left it means that you are in an area which does not have 4G support. When you are in an area with 4G (or, on Verizon, LTE) you will see that in the top-left corner instead.

T-Mobile's 3G/4G coverage for an iPhone 5 is better than a year ago but still limited so you are rolling the dice. They just released a carrier update for the iPhone that will give an iPhone 5 access to some of their 4G network. But it's still early days and the usefulness will greatly depend on your location. T-Mobile also offers a pay-as-you go plan ...

No. The LTE standard uses different frequencies in the US and Europe. However, the model sold in Europe is the US model. This has been officially confirmed by Apple [1, german]. LTE in the iPad The iPad supports only the frequencies 700 and 2100 MHz [2] for LTE use. These frequencies are not used for LTE in the EU. If you take a look at the footnotes, ...

iPhone 4S supports HSPA+, while iPad 2 doesn't. HSPA+ is technically not 4G, but is being advertised as 4G by networks like AT&T and T-Mobile in US. Pre-iOS 5.1, Apple wasn't calling HSPA+ a 4G network, but they have started calling it 4G now to match AT&T's other "4G" phones that are using the same signals and protocols as the iPhone. If you are ...

The short answer is yes - the 4G on the iPhone 4S is merely a label change for AT&T's HSPA+ network. More info can be found in this Apple.SE question. From Apple's specs page for the iPad 2: Wi-Fi + 3G for AT&T UMTS/HSDPA/HSUPA (850, 900, 1900, 2100 MHz); GSM/EDGE (850, 900, 1800, 1900 MHz) From Apple's specs page for the iPhone ...

They use the same network and speeds will vary depending on how AT&T allocates bandwidth. Too much is made out of theoretical speeds and not enough about actual, "real world" results. All carriers (and ISPs) throttle bandwidth depending on various factors (network congestion, area, population density, etc.). And you'll likely see no difference between ...

The "o" means that you're on a 2G network. In Verizon's case, that would be 1xRTT. If you see it on an AT&T device, that means you're on GPRS. Here's a screenshot from the iPad User Guide detailing what the various signal indicators mean: "3G" means exactly the same thing on the 1st generation iPad as it does on the 3rd generation iPad. However, if ...

On CDMA networks, the ° symbol means that you're connected to a 1xRTT network. You might not be able to receive calls while transferring data over the network. On GSM networks, it means that you're connected to a GPRS network. This Apple support article goes into further detail on possible connectivity indicators for different cellular networks. For your ...

I'm not sure. But what I do know it the fact the battery in the new iPad has 70% more capacity and people describe it as massive. It has a massive 11,666mAh (the iPad 2 has just 6994mAH). The same battery in an iPad 2 would give... To put that in context, an iPad 2 with with this new battery, if such a device existed, would probably last close to 17 ...

The 5.1 update provides a labeling change for iPhone 4S users - "3G" is now "4G". As the other answerers have noted, HSPA+ is technically considered a 4G technology. A MacWorld article states: The 4G label in iOS 5.1 instead reflects AT&T’s perspective, namely that the carrier’s HSPA+ network (also known as Evolved High-Speed Packet Access) ...

Here's an article that specifically mentions that the new iPad will not support 4G connectivity in Sweden: While there has been a rapid build-out of 4G networks in the U.S. and countries such as South Korea, LTE is still scarce in Europe. Even in Sweden, one of the few European countries with broad LTE coverage, it seems users of the new iPad won’t be ...

Sadly the term "4G" has been co-opted by marketing, and it's hard to know what anyone means when they use it. Gizmodo reports that here in the UK, as in the US, each carrier has a different 4G standard, and the iPad 3 as sold here may not work with "4G" on any British carriers. Apple have crammed a huge number of radio protocols into that thing, though, so ...

You can use T-Mobile's "Individual Plan". They offer three options. The first one is 50 USD a month and comes with 500 MB of data. The second one is 60 USD a month and comes with 2 GB of data. The last one is the unlimited one and costs 70 USD per month. Here's the link to their website if you want to check it for yourself.

This will depend largely on your carrier. If they're offering 4G/LTE service with the iPad 3, you may need a new SIM card. If they're not offering that service in your area, it shouldn't matter if you have a new SIM card or not. Your best bet is to ask your carrier.

The Apple website states you need a: Micro-SIM card tray Same as the iPad 2. So I'm pretty sure the cards have the two dimensions. Otherwise their would have been some complaints about not fitting the SIMcard.

I'm not sure about the length of the battery, but I have some anecdotal evidence that may be useful. The iPad was fully charged at 6 AM, but I didn't use it until 11. By 3 PM, after watching two episodes of Game of Thrones (55 and 45 minutes long) among other things, that battery was showing 20% charge. I have push email off and no notifications, and I ...

Yes, if you upgrade, you will have to jailbreak your device again. Updating your device will restore your iPod Touch to its default settings, removing any and all jailbreak apps and cracks. But I've been told that an iOS 6 jailbreak is available so you should be able to do it all over again.

As of version 4.4.1 (current latest version), Documents by Readdle only requires iOS 6, and therefore should work on your device. The books in the iTunes books section will only sync with iBooks. Simply un-sync that section, since you don't have iBooks installed. Download, install and open ’Documents' on your device, then go to the Apps section, scroll down ...

"Standard 4G" is kind of a meaningless phrase. According to this article, disabling "LTE" means it's limited to either CDMA 3G or HSPA+. HSPA+ is supposed to have performance comparable to LTE, so I would guess that if you disable LTE and see a "4G" icon, it means you're getting HSPA+. PC Mag confirms that Apple (like their competitors and partners) ...
