I've been struggling with this the last week too - and with data usage.
I've always had my mobileme set to push on my ipad - it never seemed to impact battery life, so it does more on the iphone? I've gotten spoiled....
I'd like to have an indoor brightness setting, and an outdoor. Indoor i find it too bright (i run my ipad all the way down), but then i forget and can't use it in the car! Which brings me to... why doesn't the iPhone have the brightness in the double-click home thing? I keep doing that.... UGH! LOL!!
I don't want notifications for most things, if i leave them "on", but then turn off for each app does that work?
I thought i had my phone set up the same as my iPad, but i'd used 250mb of data since late January on my iPad, and in 8 days on my iPhone i've used 703mb without using any streaming music, and about 45 minutes of NASAtv on Friday! It makes me very happy i have unlimited - but gee, what is sucking the data up?? I'm at home with wifi 80% of the time by my guess.
I"ve been unplugged for apparently 1h 29m, and its been used for 37m and i'm down to 94%. I'm sitting next to my wifi router and have 3 bars of service.
I'm just very thankful that my daughter minded me i had a car cord for my touch - because i'd be in trouble on tuesday going out of town for the day!!
Thanks for any other tips to try to extend it out.
