That size limit is based on the size limit imposed by the network. The operating system has to make sure that the MMS size is equal or lower than what then etwork will allow (or then etwork will reject your message).
Actually The limit can be raised, because if we test a MMS 10 second video it is like 400k+ which means that the message size can be larger. (you can see the video size after recording to verify this and then send with the default app).
However, I don't know the specifications with MMS technology standards. There could very well be set limits on different media in them essage (only this much space for text, this much for audio, this much for video...etc).
But if other networks do not allow this much data, I don't know how handcent can do it, because handcent works for any android phone (multiple carriers/networks) not just Verizon. You would need to be able to detect the network used on the phone to add specific settings for each carrier.
As far as I know the default message app does not have a setting for the size limit of a specific message, so we can't rely on that, either.
Ah, but where do we find the setting and change it? My guess is it's not available to us users. What's frustrating, is my mom is on Verizon and can take and send me a video from her phone (a flip type phone, not a smart phone) and it comes through. 27 seconds and 539kb. I can't can't take crap and send it.When it comes to my kids, this is a real
If its a big problem, you can always use the default app to send a 10 second clip through MMS. And just to clarify, I don't think we can break the limit on Verizon's MMS messages. I just think our apps/software is not optimized to take advantage of the full size the network will accept. But obviously if we can send 400k+ videos over MMS, the size is clearly over the 300k mentioned earlier.
If you email the guy from the market page for handcent, you guys might be able to convince him to look into it. From my talks with him, he seems to be somewhat interested in fixing it, but lately hes been working on improving that greeting feature with a bigger selection and such.
