Just rooted my phone for the first time using the adb method. Was easier then I thought it would be.
Now the hard part is gonna be getting some froyo'd voodoo roms onto my phone.
Now I have a couple of questions:
1. Will my SD card get formatted?
2. What will happen to my phone contacts and if they will disappear when I mess around with new ROMs, what should I use to back everything up? Is it titanium backup?
No your card wont get wiped.
there are alot of ways to back up your contacts...
i would def use titanium back up
also you can export to SD
From contacts press menu button>import/export>Export to SDcard
also you can sync gmail contacts
Settings>accounts & Sync>check off auto sync>then select your gmail account lower in that screen>then check off contacts and let it sync
then go online and check your contacts secton of your gmail account to make sure it was a good sync
you can also use Backup assistant
Settings>accounts & Sync>backup assistant>backup
