A fine morning I bought k 750 i.Good looks tarrific ring tones and great screen resolution but.......it hangs a lot. My friend bought it next week.He went on a tour.Switched off the phone after boarding the flight and when he switcched the phone on.....it hanged for ever. Sony ericcson replaced the phone-----but the new one has same problem. It is hungry for power.Even with minimal use bettery whenever you try to open the back cover it takes your power and time............... When you want to use its GPRS you have to call your operator several times its not as easy as nokia. DONT UPGRADE MEMORY STIK TO 512 mb THE PHONE WILL BE SLOWER. DONT RELY ON CAMERAS PICTURE GETTING ALWAYS STORED!!!! I HAVE LOST SEVERAL IMPORTANT PICTURES....... ITS PC SUITE ----WHEN YOU SYNCHRONISE WITH PC TAKE CARE----ALL YOUR E MAIL ADRESS WIL GO TO PHONE AND WILL FILL UP THE ADRESS BOOK IT HAS EXCELENT FEATURE.YOU CAN SEND ENGAGE TONE TO UNWANTED CALLERS-BY CHOOSING OPTION OF INCOMING FROM LIST ONLY OPTION.NO ONE WILL FILL BED AND YOU CAN AVOID UNNECESSARY CALLS.....................
after 1 year use I have to clean the phones contacts with contact cleaner evertime I connect hands free/charger.
