Vin's ROM installed/Tmobile...questions.

[TheKid1]

Ok I installed Vin's ROM. Works great. Finally got the Tmobile service working too thanks to you guys. I just have a couple of questions on these 2 things. I noticed there is no task manager anymore. The reason I want it is because when I go to the start screen and it shows the programs running, when I go to close them not all close. So I was going to force them to stop running with task manager but can't find it.

So:

1) Where is task manager or why can't I close some programs on the start menu?

2) Why is those opposite arrows that are located next to the signal strength always on. It seems the phone is constantly sending and receiving data. When I turn the data button off it stops but when I had sprint and the data button was on, these arrows would only be sending and receiving when I send and receive email or use the internet? I also use automatic weather update but I've got it set on every hour so usually with sprint it only sends and receives every hour....weird. Anyone know what is up? This is going to drain my battery big time. It seems it's constantly sending and receiving. I"m actually not sure if it is the custom ROM or Tmobile.
