I have Skyraider 2.52 Sense and 250mb free for apps and NO social apps. The main reason I did not wait for the OTA was the "Low on space" problem on 2.1, yet Android STILL has the problem with 2.2!!
I have had Froyo installed for less than two days and already getting the error. My contact list is also small and only 25K in ATM.
This is getting very old.
