[TwinEdge]

Hi to all,
Well guys I have a question...
I have a ppc with these specs that had
already been installed in it by someone
else:
I don't know if it's unlocked..the guy told me it was..
but for some reason i don't believe the dam guy...
(getting lots of freezes and doing lots of hard resets)
No joy!...

HTC Herm100=Cingulars 8525
Rom version : 3.62.502.20 WWE
Radio version 1.16.00.00
Protocol version : 32.53.7018.014

And I want to better it, what can I do?
Plus I would like to have GPS runing
on it, if possible...The GPS I know it
came with and would like to see it
working...Any ideas?

thanks...

I got this in a trade i did for a dual indash dvd,
in the box..

Hey guys I know you want us to read...But it's not only to read you got to study things before you get in to them and I've done this before in a motorola...But with this one it seems a bit more complicated.And since I don't know what has been done this this ppc ,I'm a little skimy about doing this...
I've been resetting this since I got it..So my thoughts are to use the sim unlock for htc herm,and use this rom Hard-SPL-V7...Any thought...thanks
