For 2.2 Market issues, use this mod.
For those of you having trouble seeing protected apps, I modified our fingerprint in the build.prop. What this does is spoofs the market into thinking its seeing a Droid 2 (with Froyo) It worked for me, let me know if it does for you.
1. Put build.prop into your AndroidSDK\TOOLS folder
2. Connect via USB.
3. CD (Navigate) in CMD to your tools folder
Copy and paste this
4. adb remount
5. adb push build.prop /system/build.prop
To test before you push the build.prop fix, search the market for Us Bank. If only 2 or 3 show up, you are not getting the full market. After this fix, you should see 10 items listed when you search for Us Bank.
Hope this helps.
This can also be done via Root Explorer.
Thanks to Jcase for giving me the original idea way back when. I just basically applied his Eris Market Fix to work with our phones.
