Hello all, I recently got from a friend an iPod touch 2nd gen 16 GB. I never thought I would like the iPod but I love it. Now, I have been contemplating changing my wireless carrier for some time already due to some many disagreements and dissatisfaction... but I digress. Considering getting an iPhone but I have 2 major concerns: 1. I use the internet a LOT and my iPod touch, since it is not a phone, obviously I use the 802.11 wifi... well, this sucks my battery dry VERY quickly. I get MAYBE an hour and a half. I know that 802.11 adapters do use quite a bit of power - much more in general than using data connections on phones... and that's where my first question comes up: Will I get very good battery longevity between charges if I use internet and games and such a lot? How does the iPhone perform with regard to battery life - assuming I will not use the wifi because I will have a data plan? 2. Only other concern is I MUST be able to sync all my Outlook information through Exchange. Will the iPhone sync with my contacts, email, tasks, notes and documents? Thanks in advance.
