voipover 3g

[Sandman58]

Hello
here is my "problem"
Iphone 3g jailbroken, unlocked, with 3.0 running.
I installed voipover 3g, mobile substrate, and
skype. I can not get skype to work on the tmobile
edge network. I've done a lot of reading,
and I understand that it should work, but all I get
is not connected to the net, or sometimes it says
no sim installed or no sim card.
I installed all the required apps.
Could this be a problem because I am on a yearly
tmobile plan. as opposed to a monthly?
If not does anyone have a solution or maybe a reason
why I'm having this trouble.
Another question I have, is that some of the installed
apps I have seem not to be in the correct place, like
mobile substrate is not in the system folder
nither is voipover 3g.
thanks for any assistance.
BTW I'm and old guy but really hooked on this damn
iphone..
