I'm obtaining repair estimates. Meanwhile my old pre plus is still operational and would like to use it for a few days. Is there any way to prevent it from wiping out my present profile once I start using it?
You could try not registering your Pre Plus for using it temporarily. Just run the activation bypass tool. From what I heard backups won't go back from a newer 2.x device down to the Pre, so you may have more problems than it's worth if you try to log on normally. If you do, though, make sure the Pre 3 can't connect in any shape or form to the Internet or to SMS, otherwise it'll receive a wipe message.
US based repair will cost almost $400 dollars. Looks like I'll have to move to another smartphone platform. I know I could buy another pre 3 on ebay but with the lack of a case that allows touchstone charging I could face a similar scenario again shortly. I still have a touchpad and will keep an eye on openwebos. I'll wipe my old pre 3 and sell it for parts.
