I have used Appbrain since I rooted, it's one of the best tools to have if you switch from ROM to ROM.
Also, I installed CM7 and it's funny how some apps show on Appbrain, but when you try to install them, these cannot be downloaded through the Market. Reason is some of these apps only work with 2.2 and 2.3 is not working specifically for that App (supposedly, I'll get later to that), then the Market locks or in other words it doesn't allow those apps to be downloaded from a 2.3 ROM. This is convenient for the App developers since they can work on 2.3 and not hear any complaints about all the issues their apps have on 2.3
Anyway, I traveled to LA recently and found the best radio station ever (for the music style I like), I found iheartradio on Appbrain and tried to DL through it by going to the Market, it didn't work; then I tried going through the Market App on my phone, the app doesn't even show, it is blocked by the Devs request; iheartradio at that time was not compatible with CM7 or any 2.3 ROM, it only worked up to 2.2 and it was specifically on the App description. Recently the Devs finally released it for 2.3 and now is supposed to fully work with 2.3, but I tried downloading it through with my CM7 ROM just to find out it cannot be downloaded, it's blocked!!! Very frustrating, but found a workaround:
- Went to my first rooted ROM
- 'Sprint Lovers' which uses Sense and GB 2.2
- Downloaded iheartradio, worked perfectly on 2.2 with Sense
- Backed up this app with Titanium Backup
- Went back to my CM7 ROM and restored iheartradio using Titanium Backup
- The app works perfectly with CM7!!!
There is another app XFINITY TV which I found only works with 2.2 per the Devs, but did the same workaround through 2.2 and restored on CM7. The app works perfect on CM7, I don't know if other 2.3 ROMs will have the same success, but is so fast now I'm truly enjoying my remote through my phone, pretty awesome.
