I sent in my Nexus S to Samsung UK for 'repair' for the third time. The first two times the PBA was not replaced - only a 'software upgrade' was done, even though the second time 2.3.4 was available they 'upgraded' with 2.3.3.
I sent in my Nexus S in again due to the bootup issues, after I had upgraded to 2.3.4. Incredulously, they sent it back with 2.3.3 so I am back to square one!
I am not happy at all. Google and Samsung needs to pull their finger(s) out and do something about this issue. Its gone on for far too long.
