Delete SMS on Motorola W220 with Arduino

hi,

i have found this: "tutorial: send sms arduino using old motorola cell phone" @ http://murchlabs.com/send-sms-from-your-arduino/.
so rebuild use in 1 of current projects. works , receive messages have 1 problem, delete command not work reliable. in cases not delete messages, until had bypass increasing index every time, works until arduino restarts not saved permanently. quit bizar mobile phone (motorola w220) shows in outbox folder every sms green arrow means has sent sms above there kind of passage prohibited sign guess means couldn't send sms, although receive every time right message.

does know or has experience this? have tried find other commands deleting messages, found "at+cmgd=?" while ? index of sms want delete. knows site complete list of commands or command deletes or sms?

and how can display response phone correctly on computer e.g.

code: [select]

serial.println(phone.println("at+clac"));
this print number guess "11" on screen

i looking forward hear you.

king regards
