...Had been using it for 2 days now. Seem ok. Touch wood :)
Congratz, you scared me there for a moment :)

Next project would be my dad's k750i which he got cheated by the authorised SE people. Send in for repair and yet those unscrupulous SE technician mess it all up and charge him exhorbitantly. You have this phone ?
k750i is DB2010 so you should read the same guide as for K610i, but the DB2010 part, never done it myself, but the guide is proven to be good i think.
