So I did the upgrade at home, no problem, then loaded My Back up from the market, and reloaded my apps and data from my SD card. I got all the way to load HTC home (109 items). At item 107, force closed pops up. Now when it goes to load the home page it's an endless cyle of forced closed. Took it to the Sprint store, nothing they can do but reload the 2.1, come back in 2 hours . I do, go home and run threw all these steps again, but this time without loading the task killer app (store recomendation). Same results! . Any suggestions?
