I've just got my new Android phone a few weeks ago (Woo Hoo!)
.. and i've rooted it, mainly cuz i wanted to put Hebrew on it.
I finally managed to get it to work, and now i have SU permission.
the only problem is,

I can't surf the internet.
I am able to connect to a wifi network, and do anything else on the phone-
but for some strange reason- i can't get internet.
that means no market, no google maps, nada.
My system:
Motorola XT701 (similar to XT720), Android 2.1-update 1,
kernel system 2.6.29-omap1
