I sucessfully updated my 1.1.4 iPhone to 2.0 using the pwnage tool over the weekend and everything seems to working just fine-except for push E-Mail via MobileMe. Even MobileMe contact & calendar sync a works just fine on the iPhone with changes propagating both to and from the iPhone almost instantly pretty much all of the time. However push email has all but eluded me. Everything I've tried and so far no push email. I have to press the email app for the emails to download. The rest of the time, push email simply doesn't work for some reason on Wifi or on Edge thru T-Zones Proxy hack. I have setup, removed, replaced and tried to get this to work using two seperate MobileMe accounts, on two different iPhones. Still, no push email. I even tried an MS exchange account thru web2mail with no success in pushing. Yahoo push has never worked in 1.14 or 2.0. I am almost sure that this isn't something that is caused by the fact that I'm using a proxy via T-Zones since most of the time the iPhone is connected via WiFi rather than the mobile network. Anyone else with similar circumstances have better luck with this? In other words, is there anyone that has a 1.0 iPhone with 2.0 FW that is unlocked, Jailbroken, and using it on something other than AT&T successfully getting push email from MobileMe or any MS exchange service? If so, please elaborate if it worked from the start or your experience. Thanks!
