Total noob question (I searched 1st)

[soIsezto'emIsez]

BTW, whenever I search for anything, I get this:

"The search term you specified (to) is under the minimum word length (3) and therefore will not be found. Please make this term longer."

Even if I use 5 words. Weird.

Anyway, I bought a used PPC-6700 and it has WM6 on it. According to the Device info it is ROM version 3.50.00 WWE, ROM date is 4/25/07.

Anyway, I want to switch my service to this phone but I've read that I can't do this unless I flash back to WM5 because the WM6 won't supprt the ## commands that are necessary to program for the ESN switch. Is that true? The guy I bought it from said WM5 is on the storage card, but how do I do it (if I indeed need to do it)? Thanks.
