APRSdroid for the Mobilinkd TNC2 works great! I have been playing with the software and I like it. It is pretty easy to use and configure. I am always happy to see software for something other than Windows. This software downloaded and installed on my HP8 tablet with no problems. The software is not free, but is worth the small amount for it. I have no problem paying a little for software, when it is not for windows. All of this put together is becoming an easy way to get into APRS. Try it and see!
