MMS disappeared?! iPhone 3G 4.2.1

[ph3n0m]

Today I just noticed my mms has disappeared, the camera button in sms apps, no option to send mms in photos, no mms options in "messages" settings.

Help would be appreciated

No I use h20 wireless. but like all the options literally disappeared like my phone doesnt support it, but it does

Can I take it that H2O is not an official iPhone carrier?

If so, this is an issue with UltrasnOw.

Pop out the SIM tray, push it back in, then report back.

H20 is an mvno of at&t (you can activate an iphone with an h20 sim), I had mms on my phone like yesterday, but for some reason it disappeared.

alright I feel dumb now... something deleted my mms settings in the cellular data network tab, after i re entered them, everything showed up

I too have the same problem. Jailbroken 2 iphone 3G. And unlocked them for Walmart family mobile (tmobile). iOS 4.2.1, and both of them have no option to send an mms. I had read somewhere that the iPhone 3G did not support mms, but can't remember where I found it at. Tried to install irealsms but it crashes the springboard. If I could get these iPhones to do mms it would be great. I bought them for my wife and I.
