Ah, yes...that annoying little battery....and what will be the life of that little booger? Especially if you're using the phone as an iPod? I haven't seen a lot written on this subject (forgive me if I missed a thread). In any case, there is NO way to swap a fresh battery when iPhone is low on power.... To me this along with the high cost of the data plan is a real deal killer. Hopefully the next gen iPhone will address this issue. I get nervous thinking I have to mail my $600 phone in to change a tired battery. (especially when I'd be without my phone)
