I found this solution better as iOS can change the usage of description in future versions, so using description property on data can be unreliable in future. We can directly use this by creating hex Token from the data token bytes.

 - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
 const unsigned *tokenBytes = [deviceToken bytes];
 NSString *hexToken = [NSString stringWithFormat:@"%08x%08x%08x%08x%08x%08x%08x%08x",
                  ntohl(tokenBytes[0]), ntohl(tokenBytes[1]), ntohl(tokenBytes[2]),
                  ntohl(tokenBytes[3]), ntohl(tokenBytes[4]), ntohl(tokenBytes[5]),
                  ntohl(tokenBytes[6]), ntohl(tokenBytes[7])];
 [[MyModel sharedModel] setApnsToken:hexToken];

}

We can also store the device token in our NSUserdefaults and use it later to send it out to our server.
