    I have read on xda that some ppl didnt wipe data before installing 2.2 but I wanted to get opinions before I go for it.

    For AOSP definitely, but probably a good idea anyway. I wiped for Super Clean.

    I Titanium'd back Need for Speed and Angry Birds so no big deal :)

    Alright thanks guys. I figured that was a for sure, I just saw quite a few ppl that said they didnt in xda and wanted opinions in here from ppl I know. I've been using the "my backup root" but I think for a change this big I'm going to use tb because that seems to be what I've heard everyone using. Thanks again guys.

    Here's my experience:

    I had Supah Clean + Stupid Fast Kernel.

    I nandroided, wiped cache partition, and dalvik. I installed the Leaked Version of the DL30. No issues.

    From there, I nandroided, wiped cache and dalvik, and then flashed Supah Clean Froyo. No issues, except for one: Periodically, my CPU goes to 100% usage, and the device gets hot, and starts gulping battery.

    I not once wiped data. On each new flash, I lost my widgets, and had to replace them. On the DL30 leak, I lost ROM Manager (Had to reinstall for some reason, the APK was there).

    So, your mileage may vary. I wanted to push to see what could be done, and how far you can push it. If you can tolerate losing your settings and whatnot, go for the complete wipe-then-install. It's the safest route.

    But, if you couldn't stand losing any of that, you probably shouldn't be trying this at all :)

    yeah data wipe is one of those things, that if you dont do it...you might get away with it...but realistically if you have an fc/problems you wont know for sure what caused them, and its likely they came from conflicts

    FWIW, I installed the first leak and then SuperClean 0.5 of the leak without wiping and didn't have any issues. I mainly wanted to try it out real quick, when Superclean 0.7 was released and it was stated that the e-mail FC issues was fixed, I wiped data and then installed.

    When I done my wifes phone, I wiped straight off the bat but I went to SuperClean0.7 right off on hers and I knew she would be running that ROM for at least a week or two.

    I'd do it just to be safe.

    You may be able to get away with it, but you just never know. Like I said previously, I was purposefully pushing the envelope here.

    Agreed. Fixing permission sometimes might fix the odd FC here and there but when in doubt wipe data. If coming from 2.1 to 2.2 just make sure TiBu is your friend and once in 2.2 just make a good nandroid/backup. In fact depending how [can I say anal on this family friendly site] you are some people make backups with greater frequency than others, daily versus weekly.

    So, once on leaked DL30 kernel/ROM, its just a simple ROM flash to a different ROM (AOSP/SupahKlean, etc).... ???

    Once on superclean you can flash the next superclean right over it. In that specific case data wiping is not required per se. Recommended by some but not strictly required. However, aosp is a different animal. If you are on superclean or aosp and want to switch to the other data wiping then in that case is mandatory

    You can restore data from user apps like angry birds, just not system apps. My angry birds progress is intact on froyo :)
