Hi, Currently I'm running a 2.2.1 jailbroken iPhone. I would only want to upgrade to 3.0 if I had a 3G S. Here are a few things explaining why 1. Landscape keyboard - although it seems awesome, I'm well versed with using the normal keyboard. I also am typing with my phone a lot while doing something and it's hard to type landscape with one hand. 2.) MMS - I've managed to not use it for a year and a half now. I never really used it before either. 3.) Spotlight - How hard is it to find something on a phone? 4.) Voice Memos - Have two apps already. 5.) Improved Calendar - It's not too shabby as of right now. I have like 3-4 things on it per week as well so it's not my full time personal assistant. 6.) Buy Movies, TV & Audio Books - The first two I might as well wait 'till I get home to download. Those two things are going to take FOREVER. My YouTube app takes forever and the quality isn't even good. 7.) Enhanced Stock App - OKAY APPLE, I'M SOLD. No, I'm not. 8.) Tethering - I have NetShare. What I do want 1.) Cut, Copy & Paste Also, redoing jailbreaks are a pain, at least for me.
