H2O Wireless MMS Problem

Herro there,

So I just recently (like 4 days ago) switched to h2o wireless for my iPhone 4 because of the catchy $60 price for unlimited talk, text, and data. Well, I have my data working after playing with the APN settings but I'm unable to send picture messages. Any solutions for this? My iPhone is running 4.3.5 non jailbroken. And I do not have SHSH blobs to downgrade to 4.3.3. so jailbreaking isn't much of an option. Not doing tethered either. Also, any tips to increase data speeds is appreciated.

Thanks in advance.

P.S. For anyone who may ask, the catch to this seems to be the data speeds. Depending on area, I only seem to be getting .50mpbs but for me saving roughly $50 a month. This broke college student will gladly endure those speeds.
