HTC has issued another SMS update for HTC HD2. Do not be confused with the previous SMS update. It seems that the previous fix did not solve the problem of SMS stuck in the outbox. You can “hear” people calling HTC a liar for presenting a fix that did not “fix” the problem.
Hopefully, it solved the problem of SMS stuck at the outbox. Yesterday, I have a very real case of HTC HD2 SMS stucked in the outbox. It is my friend HTC HD2. It is frustrating enough for him to use delivery report to ensure that all SMSes are sent out. I will install this fix. Do let me know if you still encounter SMSes stucked at Outbox after the fix.
