I noticed that my 7250 is constantly communicating, ie, the arrows that show that data is being sent and/or received are flashing a lot. I didn't notice that it did that before i installed Pocketday. I wondered if this is normal behavior of b/c of other reasons. any thoughts??
Yes, it's normal especially if you are using any IM software.
My plain Verizon 7250 (no aftermarket software) does the same thing. There was one day when Verizon did not include my bb data plan. My blackberry burned through 700 minutes in one day with the constant communication.
