Hey there, I recently purchased a used iPhone 3GS that is locked to TELUS/Koodo and swapped out my SIM card from my blackberry curve to the iPhone. Everything has been working splendidly. The only issue is I've been trying to send images to my contacts and the loading bar goes to around 75% and then it tells me it was unable to send. I'm wondering if this is a network issue? MMS is turned on in my settings. So I'm not sure, is this occuring because I swapped phones but am using the same SIM?
