Well i looked at the pictures on the forum showing the differenece between the t4242 and the t4242+ and mine definately looks like the t4242.
The wheel is probbaly fake, when i go into the engineering menu and go to keypad i just see 5 buttons not a wheel but if you press the buttons
only the right button works as down.
Mind i bought it from china on ebay, the add was for a t4288 but he also had t4242's so i think i ended up with a t4242.
It had windows mobile 6.1 on it where as the t4242 he was selling had 6.5 on it.
One other thing i have noticed is that since putting on 6.5 my power consumption has gone through the roof, the battery goes flat in a day
i have turned on all the standard options to try and save as much power as possible, when i was on 6.1 the battery lasted a week
Does anyone have a 6.1 rom for this unit as i might do what other people have suggested is the best and go back to 6.1
