What I wasnt excited about was the fact that the normal speed sims seemed to work better and possibly faster. First things first.
The problem I reported earlier with a problem getting incoming calls and SMS was still present, while outgoing calls and sms worked just fine. After some tinkering around I was able to recieve calls sms messages. But It was kind of annoying that I had to keep rebooting and calling myself until I started recieving calls. If I was away from my house phone and had to reboot for some reason, I would have no idea if I was able to recieve calls or not.
As for data, I wasnt able to test that since my father in law doesnt have the internet on his plan/sim. I assume it works though since it did for everyone else that has tried it and since no one has had problems thus far with virgin sim data. But never say never.
Now for the speed test.
Upon 15 reboots with the high speed sim, after the springboard loaded it took roughly 2 - 4 seconds to get signal bars but would take another 10 - 15 seconds to show the carrier as T-Mobile(not sure if that matters at all).
Upon 15 reboots with the normal speed sim, after the springboard loaded it also took roughly 2 - 4 secods to get signal bars and would instantaneously show T-Mobile as the carrier.

So in conclusion:
both the high speed and normal speed seemed to take the same amount of time to get signal, but the normal speed version was a lot faster at detecting the carrier name(again Im not sure if that matters).
Although both high speed and normal speed work, the high speed would not work with newer 128 BIT Tmobile sim cards and required an old US TMobile sim to work(in which the use of an old sim has always caused a problem with my voicemail alerts).
Although I have experienced a problem in both high and normal speed in regards to problems with incoming calls and sms, the normal speed sim seemed to be more stable and less prone to this error.
I was unable to compare the speed of how fast the two regained signal when going through dead zones as I didnt have any dead zones to play with while using the high speed viginsim. But if it is anything like the normal speed(would expect it to be faster) then you will be more than happy.
Im hoping that in the future the high speed virign sim will be compatible with newer us tmobile sim cards, as this limitation would alienate a large sum of tmobile customers that have the newer sims such as myself.
When this problem is solved and a new test sample is produced, I would be happy to test it.

BTW @ all other testers: Has anyone else experienced anomaly that causes the loss of incoming calls and sms while using the virgin sim?
