J2ME/Getting the IMEI or not ... Many midlets programmers are faced to the problem of getting the phone's IMEI.\\ Well, some phones support this through getting system properties or using a legacy api. Other's (e.g. Nokia S60) don't support this.\\ I think the only usefull thing you can do with the IMEI is for registering a midlet so that a registration key is bound to a single phone.\\ One idea that came to mind is:\\ If the phone supports bluetooth (JSR-82) you can use the local bluetooth address. {code} String address = LocalDevice.getLocalDevice().getBluetoothAddress(); {code} This address should be unique. The only problem is that this only works on phones supporting JSR-82. \\ \\ On Nokia S40 3rd Edition devices you can query a system property: ~~com.nokia.mid.imei~~ e.g. {code} String imei = System.getProperty("com.nokia.mid.imei"); {code} Only available on S40 3rd Edition devices. (Not in 6270 and 6101). Returns the device’s IMEI code.\\ ~~Note: The MIDlet must be signed, otherwise this value is NULL.~~ 2006-01-13 11:35:07.871 2004-12-13 13:20:03.965
