$200 with a two year plan
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.
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.
If you've been with AT&T for atleast a year it will cost you $200 and a two year contract.
no the iphone is much thicker
The iPhone 2G is much slower than the iPhone 3G.
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
2g is 2nd generation 3g is 3rd generation. 3g is much faster. iPhone 3G can support WCDMA and HSDPA frequencies, but the iPhone can't.
The iPhone 3G was released on July 11, 2008 The 3Gs was released on June 19, 2009 and was an upgrade
