So I plan on getting an Iphone this friday, and I don't have AT&T at the moment, so I don't really know them as a provider or how they really operate. Should I purchase my plan and everything when I buy the iphone or what? I don't have a lot of music at the moment, especially since my computer crashed not too long ago, so should I just get the 8gb instead of the 16? I was thinking of only putting on the necessities, as far as music goes. Roughly how many gigs is each application? I was thinking about going to the AT&T store in the town next door to me instead of the Apple store that's about 30 mins away, because i figured it would be much more crowded. Good idea or no? Idk, any other tips and such would be awesome, thanks.
