String uid = tManager.getDeviceId();

Get Ram size :

MemoryInfo mi = new MemoryInfo();
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
activityManager.getMemoryInfo(mi);
long availableMegs = mi.availMem / 1048576L;

Get Manufacture info:

String m = Build.MANUFACTURER;
 
Get Networkoperator & SIM operator name:
String m = Build.MANUFACTURER;

TelephonyManager telephonyManager =((TelephonyManager) Context.getSystemService(Context.TELEPHONY_SERVICE));

String operatorName = telephonyManager.getNetworkOperatorName();

//<------------SIM Operator------------
String operatorName = telephonyManager.getSimOperatorName();

Sim number:

mPhoneNumber = telephonyManager.getLine1Number();

Get Network Type :

if(telephonyManager.getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS)
Log.v(TAG, "3G");

if(telephonyManager.getNetworkType() == TelephonyManager.NETWORK_TYPE_EDGE )
Log.v(TAG, "GSM");

if(telephonyManager.getNetworkType() == TelephonyManager.TelephonyManager.NETWORK_TYPE_CDMA)
