Introduction
The Apple iPhone is no longer the Superman of the cellphone world, despite all the hoopla, lines and glitz. Every carrier now has (or will have) at least one comparable Android superphone, such as Sprint’s EVO 4G, T-Mobile’s Google Nexus, the upcoming Droid X from Verizon on July 15, and Samsung’s Galaxy S from either AT&T or T-Mobile later this summer. Plus, the iPhone 4 also has to compete with the lower-priced 3G S, which also can run the new-and-improved multi-tasking iOS 4 operating system.this iphone4 is great with her style. It was a pricey gadget purchase at over $500.
Sound quality :
We could discern no qualitative improvement from the 3G S, but the speaker did pump out a bit more volume during FaceTime conversations. In a quiet room, we didn’t even have to go much beyond three quarters of maximum volume.
