I'm having the problem of the light staying purple (or blue if I'm color blind) and asked Amit on the Facebook page and he replied with the following. I haven't tried it yet so don't know if it's the answer or not.

Flytrex Hi Jerry smile emoticon My first assumption will be to check the APN configuration in the Live device and try configuring it to use the H2O APN settings. Technically the Live includes a built-in list with APN details for most networks world-wide, however, it is missing many of the APN settings for smaller virtual networks. Since H2O are a virtual network (using AT&T's network) it is likely that you will need to setup the APN settings of the Live device manually at first.
After settings up the Live APN settings give it another try. I believe there are good chances this will help solve this issue.
You can configure the Live APN settings using the Live Programmer available for download via our web-site here:
Flytrex Live 3G Programmer
Let me know if this issue continues and we'll check a few other configuration options that I believe might be related as well.

As far as dealing with this company I've always got answers to my questions, both email and on Facebook. Sometimes not as quick as I like but no longer than 5 days or so. I had to have the one for my P2 replaced as the CAN-BUS adapter was defective and burned up both my video transmitter and the Flytrex 3G but they replaced the adapter and 3G with no problem.
They are a very small company and I doubt they even have 15 people working there. Like most sellers they have their products manufactured in China then they check each one to make sure it works so it does take time. If you monitor the live flights you can see one of them coming on line with what looks like a short flight to nowhere which must be quality checks. I too got very upset over the Live + even understanding their change from a "open up the P3 to a plug and play adapter but still they shouldn't be taking folks money until they have the products ready to ship. Some waited 4 months and that's just not an acceptable way to do business.
