I am a palm pre' user and have downloaded the iwatchmobile pro to my laptop. When the iwatchmobile pro came out i bought it and i got the server link. I have had a lot of trouble trying to get it to work until i found my problem. Maybe it will work for you. Iwatchmobile pro requires 3G network connection. The problem i have seen is i will have a full row of bars but it didn't mean i had a good internet connetion. On the pre' when you are in a good connetion EV, 1x etc will be seen next to the signal bars. That's when i was able to connect to the x10 server. I'm sure of it now because i have been testing the theory all day in different location. Just with full bars i would get 500 error but when i had EV beside it i connected everytime. Roaming appears to work best as long as you have data roaming enabled. i hope this will help everyone. It works.
