[Q] cannot send mms after new update?

[simba33]

Anyone else having this problem? I was rooted on 4.1.26 (<i think that was it). and updated and rooted on the newest 4.1.57 using a guide here. Well I tried to send a friend a picture and it keeps coming up with an error. I also heard the tethering workaround using a custom apn wont work anymore either (havent tried myself). but I just wanna know if im the only one experiencing this or not, and if im not alone is there anyone with a solution? I am new to this forum and to android (changed from iphone).
