Tex,
The iFly 520 does not currently support Bluetooth or Wi-Fi. You can use our iFly Connect on any internet connected PC. I've seen many FBO with an iFly Connect icon on the desktop. You'd just need to make sure you have the SD Card adapter or a USB based SD card reader.
iFly connect is extremely fast when using an internet connected PC. You could have Weather, TFRs, etc updated and be ready to fly again in just a few minutes. Also, the iFly 720 supports Wi-Fi for this type of benefit you are asking for. I hope this helps.
