I know that we can control the output connected to the 8051 ports through mobile by interfacing DTMF decoder 8870 with 8051 .....but can i get information of some inputs connected to the 8051 to my mobile by interfacing any other device with 8051??.....
if yes ,please help me out by informing about that device.......?

Yes you can get informations about the input of the microcontroller on your phone.
Read about sim300 or sim900, there are a lot of GSM modules which can be safely interfaced with the micro troller for calls and SMS.
