I want to use an original (non jailbroken) iPhone4 to access the internet with an iPad.
This should is possible using the Personal wifi hotspot included in iOS 4.3 as mentioned in Tethering iPad to iPhone, however some providers (such as the Dutch T-mobile) have removed this feature in a localised version of the OS.
Is there a (legitimate) way to update to a "generic" iOS so I can use the Personal Hotspot to tether my iPad or is there another (legitimate) way to not have to get the 3G iPad and an extra sim card.
Please note I am in Europe, i.e. not on AT&T or Verizon
