I have a HTC Desire GSM and a Xperia X10i.
I have already using LeeDroid Gingerbread custom ROM on my HTC Desire and now working on Xperia X10i.
Rooting the Xperia X10i is straight forward using Single 1 Click 1.9 and does all the tricks. However, working on XRecovery on Xperia X10i needs some tricks and I have found those posts above useful.
Thank you so much guys. I have managed to install the XRecovery on third attempts, and now by the time I am writing this comment I should have backup the entire stock ROM & Apps + seetings.
My first aim to load CM7 for the Xperia 10i
Happy rooting & set my Xperia freeeeeee
