That doesn't make sense Siacona..if everything else is working fine except AIM , why is it that it is Boost's fault? If you have no problems accessing other ports with your handset and the attempts at getting into AIM are rebuffed than in my mind I the problem has to do with AOL.....

What I am suggesting is that , just as you mentioned, Aol has done something to block or prohibit access thru Boost Messenger....I believe if a "patch" is forthcoming it will self correct thru the network or the "patch" needs to be applied thru an AIM firmware upgrade....I am certainly not as knowledgeable about isp's as you are so I would suggest the place to ask questions about this, in measured amounts, is both Wireless Web support and AIM. I have given you WW supports contact # and as I mentioned there is a method of contact on AIM's site to ask about service issues....
If you would like, I will try and ask the questions but I need to know the exact error code or message you are getting when you try and access AIM, the model of handset, and the phone number effected, with this information, hopefully, WW support can offer a solution or a time frame on any network resolution....
I'm sure you are aware of the problems that arise when dealing with third party vendors...if they suddenly decide they want more money they slam a door til we the consumer pay's up, But if the rest of your wireless access to the net is up and running from your phone than Boost does not have the responsibility or the blame to shoulder for AOL's decisions.
Please let me know what you would like me to do...you can contact me directly and I can do the leg work on this or with the information I have provided you can do it, but either way please educate me and everybody else on the resolution. Thanks, Jess
