I'm not on the Mighty Rom but this is a common issue to Sprint users on all Manilla 2.5 roms. Currently the sprint network settings doesn't allow you to send/receive mms using the htc messaging client. There are plenty of workarounds for this issue.All of them use different methods. This is the workaround that I currently use. Be aware that all these fixes have side effects that will break something else. But if you must have mms, then its worth it until we get a an updated manilla through our carrier. This is what I did step by step.
1-using regEditor HKLM/SYSTEM/INBOX/EXTERNAL ACCOUNTS/SMS
tap & hold sms to edit or rename. rename SMS to SMS.htc then soft reset
2-search for the arcsoft sprint mms cab and install it (there are plenty in this site)
3-from homescreen tap on the email tab, inbox, select the sms/mms account.
once your're on the sms/mms screen press menu, pics/videos options.make sure
both boxes are checked, retrieval mode should be AUTO resolution original.
4-now on the same screen at the bottom,go to CDMA servers and make sure sprint
selected as your default server. thats all I do
Now what this does is it lets you use the native htc messaging to manage your text messages and the native windows messaging to manage your mms. If you get an mms, it will show on your messeging indicater counter. press the messaging tab to find out if it is an sms or mms. if it is sms u can view it on that screen. If it is mms you will notice a paper clip to indicate an attatchment. to view the mms, go to your email tab, swipe your finger left/right til you get to the sms/mms screen, then you'll see the sender, tap on that, then your picture will open.
Now this sounds long and difficult on writing, but it is really simple . I hope u have a good luck
