When Danny and Jamie had their fight which ended in both of them going in the canal, after Danny and Frankie pulled Jamie out of the water, Danny tried to call an ambulance, but his mobile, which was on him whilst he was punching the bejaybus out of Jamie in the water, didn't work and he threw it in the canal. Then Danny goes into hiding. When he didn't turn up at Underworld after a day or so, Liam goes looking for him at Frankie's and Frankie says "have you tried his mobile?" Cut then to Danny taking a call from Warren on his mobile. Now, assuming he's got himself a replacement phone, being in the state of mind he's in, would he have called people and given them his new mobile number? Would he even have bothered getting another phone?............ You see where I'm going with this? UNLESS....... he had another phone that Liam, Warren and co. knew about, but us viewers didn't!!! No?
