My general experience with the 650 has been excellent except for the 2 or 3 following days after an upgrade and even after having purchased it.

After some use, for some weird reason the phone never crashes. It's as if the phone has to get use to the new architecture, improves day by day and then basically works flawlessly. This has happened everytime I did a hard reset or after upgrades like 1.13 and 1.20.

Once the phone gets going, say about a month after the upgrade I can experience up to a whole month without crashes even though I use it very intensively for everything including music, GPS, instant messaging and games, appart from the typical apps and phone.

Anybody else had this type of behavior from their 650?

By the way this is an unlocked GSM in Movistar (Telefonica) Argentina.
