Ok good, i installed the app and it links up and works just fine. I have seen no problems with it.
Edited: If it really only is for t-mob it would mean it goes through their network somehow, if that is true they could just do what sprint did with it's OTA tv.. and just lock it down to those with an Ip assigned by t-mob.
Once you download it, transfer it to your droid, you can leave it on the top level or create a folder. Use Astro or another file manager to open the file and it should come up with wanting to use the appmanager, from there you can install it.
Does anyone here know the differences between WHERE and Sherpa or if ones has advantages over another in some area. I want an app that will allow me to find the hidden jewels of every city..underground and stealth but still cannot escape the app.
