I received my 5th thunderbolt refurb today. First launch device worked perfect. Sent it in because kickstand coating was peeling and small crack by front camera since I got it. Since then I am now on my 5th refurb. I keep dropping data on some refurbs, had to get new SD card from Verizon for other data issues, which did cure it for a while, now my 5th refurb don't recognise the SD card or keep data connection. What to do? Switch to Droid charge refurb? Demand a new thunderbolt? Or ask for upgrade to bionic at subsidized cost? I'm at this point unwilling to accept another refurb from Verizon. What should I do?
