I have a sony ericsson w810i came from cingular 3 weeks ago... and I wanted to customize it... and I have everything with me, i followed the very first step... but it won't let me customize because it won't detect my phone... and it says in the tutorial i have to install seus, but i heard if i use that it might upgrade my cid...

so i was wondering if it's safe to do the seus, i heard it'll upgrade my cid49 to a 51 or 52... i think. help will be thanked!
