ADMIN EDIT: Pioneer is not recalling the units, but will provide a software update as soon as possible.
After reading through all the owner issues on this forum, and other forums as well, I still decided that I could live with those annoyances and I wanted one.
I called around a few shops here in Miami and no one had it in stock, i started calling shops that were a little farther away from my home and finally found a few in stock at a shop way down south in Miami. I drove there at 12pm today and asked for the rep i had spoken to on the phone. i was told he was at lunch but if i needed help. sure, i asked about the F90BT, that i wanted one, soon after the store owner told me they were all backordered. I was a little upset now, as i had driven almost 30 miles based on what the rep told me on the phone. he apologized and let me know that even if they were in stock i shouldnt buy one. the Pioneer rep had been there just a few hours before this morning and explained that Pioneer has acknowledged problems with BT audio quality, ipod connectivity, and lockups/hangs/freezes. Pioneer had asked that all units be shipped back and that new units with either an updated firmware or hardware revision would be shipping soon.
i can understand a hardware revision needing all units to be recalled, but just a firmware update shouldnt prompt Pioneer to recall all units.
Most of our issues/annoyances, in my opinion, can be solved through software updates/tweaks. However there are owners experiencing issues that could point to hardware related causes such at BT audio not being clear(could be a problem with BT radio chipset).etc.
take this info with a grain of salt, its simply what was told to me by a store owner who, however, would have no benefit from lying to me.
