I prefer option 2. flash a factory 1.5 rom, so you'll lose your root privileges and then try to do OTA upgrade again.because it means that if I get the OTA update, I will also get all the 3 stuff which can only be accessed through their network using their rom.
Therefore, how do I flash a factory 1.5 rom, what's the procedure. Thanks for your help.
Hhhmmm i dunno which 3 stuff your actually on about... but apparently i think it's safe to upgrade to 2.1 if you have root privileges. The 3 stuff your on about...i'm assuming is the Planet3 stuff right? Well i am on 3 also and i've rooted and upgraded, downgraded fine will full access to Planet 3.
If your refering to the My3 account (Check balance), Billing, etc... Free access to Skype, MSN, ebay access, Twitter, etc... i can confirm these are working fine using the Generic Stock roms (i.e without the 3 branding, logo's, etc..)! Apparently the Planet 3 stuff are only bookmark links. As long as your using a 3 Sim card .. all these 3 Stuff may be accessed via web link and add to your favourites (in you internet browser).. the link is ... [ghp.three.co.uk] .... without the square brackets. If you want the Free Vid's section & 3 Store for music/games etc... you can try ... [mobile9.three.co.uk].... as for free Ebay access ...try [h3g.ebay.co.uk]
But your may need to dl the APN internet settings for three first... most roms have these already.. if you don't have them... send a message and i can tell you the settings.
Hope this helps. BTW i recommend for 2.1 roms... HTC Hero [RCmix v2.1] or 2.2 .. using this rom myself seems quite good... Live wallpapers, chinese support (CIME), apps to SD (A2SD)..
