Maybe somebody knows what could be the problem. When I try to sign in throught MSN messenger on my T-Mobile SDA, it starts connecting but in the end it gives a message: Sign-in to MSN Messenger Service failed because the service is temporarily unavailable. Try again later.

Maybe I should update my MSN or something? Before I updated to the new ROM everything was working fine.

The IE works fine thought, opens pages etc..

I'm having the same problem as you today, and this is the first time its failed to sign in all year. I went onto the msntroubleshoot and read what it said to alter it and I tried to fix it but its still being stupid. I'm going to wait until tommorrow to try and sign in again I think.

It seems that you may be having the same problems that a few other people I know and talk to are having. I posted about it in the Cingular Wireless forum since I thought I would start there as it could have been carrier specific, but it looks as if it isn't.

My theory is that they are cutting things over for Windows Live Messenger mobile, and this is causing a disruption with the MSN mobile services. I was able to login using Agile Messenger, and also able to get on just fine with the Windows Live Messenger Beta. Rumor has it that it is going public this week sometime. Sorry that I can't help other than recommend getting the Agile beta and using that until the WLM mobile becomes public. Hope this helps.

My phone (i-mate SP5m) is the same phone as the SDA (just not T-Mobile branded). A difference would be my phone is running the i-mate ROM.

I saw Gryphon's post the other day that he and his boss could not sign on to MSN messenger so I decided to try it out. I set up an account and have had no problems using the service since.

I sign on by selecting Pocket MSN on the start menu then the first option is MSN Messenger. That brings up the sign on screen so I press the joystick in and it signs me in. No problem. I just did it as I was typing this to verify it's working TODAY and it is. My phone is on the Cingular network.

I've never used this service on my laptop so I just went to MSN.com to install the messenger service and the download is for "Windows Live Messenger" and says nothing about beta.

The service I'm logging on to from my phone and using successfully is the one that came built into the ROM from the get go.

Oh, the WLM that is in beta is for the phone. WLM for the PC has been in swing for a while, but they are incoorporating A LOT into this whole Windows Live concept that can be completly accessable from any Windows device (i.e. PC, Smartphone, PocketPC...).
