Can cell phone companies ruin your credit?

[MelBel]

When I was 17 me and my brother moved alberta and we got a cellphone plan with Bell Mobility, he was the main person on the account and I was like his "buddy". It was a three year contract and about 6 months into the contract the screen on his cell got smashed so he sent it in to get fixed once he got it back he threw the phone on his bed and the screen cracked so he was mad and said screw it i cant afford to get this fixed or another phone..so a couple months down the road he got a phone with rogers and to this day which has been 1 1/2 years he hasn't received a bill or anything from bell about his cell phone account, nothing is on his credit about it either...and Im wondering cause I cannot afford a cell phone and bell said it will cost me 300 to cancel the account plus the 250 i owe them and i have no money for that and im wondering if i was to just stop paying them and leave it will they put it in my brothers credit report (because the contract is under his name not mine)...I understand that they will have his name on there list, and he wouldn't be able to get a cell phone through them till he pays what he owes, but he doesn't plan on going back to them cause rogers is so much better, i just don't want his credit screwed..Thanks in advance
