guys.. i've got some questions..
i noticed the APN settings are different for 2G mms and 3G mms, in my case, Celcom.. so does that mean if i use APN setting for 3G and i turn it off for 2G only to save battery, then i won't be able to receive any mms? coz i have issues in receiving mms.. anyone knows?

1stly, you must have MMS APN setting in your APN setting.
before this I just use APNdroid to turn on & turn off the APN. Whenever I want to sell MMS, I'll turn it on, then after sent I'll turn it off back. And when to received the MMS, usually we will received 1 message with "download" button inside it, before pressing download, just turn on the APN back.
Other way to received & sending MMS without turn on/off APN, just turn on & connect to wifi connection during MMS'ing.
Also, try to create APN setting for 3G and also setting for 2G. Means there will be MMS, 2G & 3G APN setting.
