Getting phone model

You need miso module.

Looking up phone model using firmware code

korakot (Korakot Chaovavanich) — Mon, 06 Mar 2006 16:49:46 GMT

You can lookup the firmware code by



dial *#0000#

For pys60 you can use



>>> import sysinfo

>>> sysinfo.sw_version()

u'V 3.42.1 16-10-03 NHL-10 (c) NMP'

>>> firmware = _.split(' ')[3]

>>> firmware

u'NHL-10'

>>>

Looking at the table here, a mapping can be made.
