Apple iPhone 3GS

If I were you I would just keep the ERIS. Once it gets the update to 2.1 it should be alot better. The Apps store grows every week so that shouldnt be the case. As fsar as the memory can't you just buy a bigger memory card? I think it can hold up to at least 16 gb then you can always transfer them to an external HD later. I think you will definately miss the full customization and multitasking the ERIS has. I have the HERO on Sprint and love it. I would never pay more for an overpriced phone thats not customizable on a network that has so many problems with their 3g service. Not to mention you can't even remove the battery on an iphone.
