I suggest calling you're current provider and they'll be able to advise on the options.
No, you can not upgrade your iPhone 3G memory.
Sorry but no, if your on PAY AS YOU GO there is no way you can upgrade. Only the plan users may upgrade.
I just upgraded from The 3G. I upgraded to the 4GS, and I love it!
No.
$200 with a two year plan
Yess you can ( but not through the itunes updates). if you are available for an upgrade, just go to the store and you can get the 16GB iPhone for $199, or the 32GB for $299. IF you are NOT available for an upgrade, each is $100 more expensive (16GB-$299 and 32GB-$399). Hope that helped! :)well i dont think you can becuz the iPhone 3G and iPhone 3GS are not the same thing. Most of the time the upgrades are free.. so yeh u cant upgrade a iPHone 3G to iPhone 3GS cuz they are both different phones.
Yes the iphone 4 is better so you should upgrade to the iphone 4.
you should i have a iphone 3g and since the 4.0 update it looks better and it has so many new features you should its awesome
The iPhone 3G was released on July 11, 2008 The 3Gs was released on June 19, 2009 and was an upgrade
iPhone 3G S = iPhone 3G + Extra's
The iphone 3g is the third generation iphone , is that what you are asking
if you bought an iphone 3g a month before the date it was in stores than u pay 15 or so to get it upgraded. if not well ur out of luck
