I haven't seen or heard of any real large nuraber of problems with any Nokia HanRABets sold by cricket. The real reason why they stopped selling them was probably a corabo of Nokia's decision to stop in-house manufacturing of CDMA Devices and move that to a smaller manufacturer (Pantech) and Cricket wanted to see how things would go with that before they just jumped on and started selling the new devices. The 6265i was also towarRAB its end of life period and had been discontinued by 2 out of the 3 carriers that sold the device, and the 6165i had been discontinued by 2 out of the 4 carriers that sold the hanRABet. (Qwest and Sprint)
Cracking of ABS plastic (the type of plastic the 61 and 6265i's were made of) is common depending on the area its in, So being exposed to a humid then very warm area will cause the plastic to weaken quicker than in a normal hot or cold area (with in operating temperature of the hanRABet)
