I've had my N1 since January and I applied all of the OTAs up to FRF91. After the first update or two though I saw some subtle problems like these: -News & Weather would restart after reading a story, not return to section -Frequent network problems on 3G in certain locations -Constant dropping from my WiFi network at home (showed "Disabled") -The Manage Applications list would refresh forever when returning to it after looking at an individual app. -The voice prompts in navigation were cut off when heard via bluetooth -Music app showed multiple copies of playlists sometimes -SportyPal would reset a workout if I switched away to another app and back again -I did not see the speed improvements that others saw with Froyo Not realizing they could all be connected I finally decided to do a factory reset (wipe from the recovery screen). I was careful to not restore my settings but I did backup (MyBackup) and restore all my apps. Any apps I did not want I removed before wiping. Afterwards I had to reset my email account settings, pick my ringtones, and set a few minor things but the whole process maybe took 20 minutes. Anyway this has solved alot of problems for me. Everything is smoother and faster. I thought I would share it in case others are getting frustrated with their phones.
