I'm getting WAY better memory management with .101 than I ever did with .77. Not nearly as much leakage. I can live with the Video Player glitch. I've noticed no other ill effects of using the "latest and greatest".
On My BB loaded with 101, in GSM mode this is what I found so far:
Prior to 101, BB service is not working other than using cinet.spcs (sprint)
With 101, BB service is now working, however it is not very stable, GPRS at times drop to gprs especially when switching between BTS.
Incoming voice quality is much improved, clear a better sound overall, however out going voice quality has problems, the otherside reporting drop out and clutter sounds.
GSM reception seems to be poorer than 126.96.36.199
Bluetooth is much improved over 188.8.131.52
So other than Unstable "GPRS", poorer GSM reception and poor outgoing voice quality, it is quite stable. I had to revert back to 184.108.40.206 because of poor outgoing voice quality.
CDMA mode is solid, it seems like RIM is making major changes in GSM Radio firmware in version 101 as compared to 220.127.116.11. if these gsm issues are solved, It should be a released candidate ??
