guys, i am planning to buy myself an iphone 4 next week. The thing is i am not sure to buy which one either the 16gb or 32gb. i am not planning to put many songs in the phone because i have an ipod for that. however i will store many apps and maybe videos worth 2gb at least. i heard that apps' sizes are getting bigger lately due to the high resolution. Maybe i will also spend a lot of time using the HD video camera. So please give me advice. Is it worth it for me to buy the 32gb ?
