How are you planning on getting it? Through the carrier where they only have 8gb? If so, will you need more space for music, media and apps?
I bought the 4S, 64gb, but will probably never use 16gb of it. I'm wondering if I'll ever use 8gb of it.
I don't game on my smartphones. Don't watch movies. Only use it for quick tweeting, tapatalk for forum surfing, banking, checkings sports scores and sms. I may eventually take more pics/vids when/if I remember to. So for me, the 4 would probably be good, but I like having the latest and greatest, especially for re-sell value.
