Hi dimiboy.

I'm going to try to answer your questions.

For anything I miss or incorrectly state, somebody please correct me.

1. There is a separate zip file that comes directly from Google/HTC on this forum post here. It is under "ERD79 to ERE27 - official update patch zip." It includes the radio update.

2. The radio update is supposed to fix some 3G issues people have been reporting.

3. ERE36B is leaked update from HTC that is supposed to add more fixes to the 3G issues.

4. RA Recovery is a recovery image that is created by the user Amon_RA. See post here. It adds more options compared to original stock recovery image, such as Nandroid backup.

5. Different roms add different apps preinstalled (some taken out, some added in), different kernels, scripts, UI elements, etc. Why they exist? Because they can. :D

6. You will lose data settings like ringtones, wallpapers, etc. Not the actual files, just the settings.

If you do a Nandroid backup, then no you will not lose any data. It'll be in 3 files: boot.img, data.img, and system.img, so you can restore it back to the state it was in when you performed a backup. See http://forum.xda-developers.com/showthread.php?t=459830

7. Nandroid backups saves everything: your settings, apps, placements of widgets on the homescreen, etc. It allows you to restore your phone back to the ROM you had before, along with all accounts/settings/apps intact. It is saved on your SD Card in a folder called "nandroid." See #6

8. See #7

9. The "standard ROM" is just Google Android, which you have on your Nexus One (version 2.1 update-1 to be exact). Sense UI is HTC's doing as they build it with Android, not on top of it. If you want Sense UI, ROM flashing is it.

Please search around for answers from now on until you absolutely cannot find one before starting a topic. These questions are very common.

Have a good one.
