If Google or OpenIAB protocol will need to add code:9 we will have a collision here
I suggest to handle it in NokiaHelper and send "6: Error" with description in IabResult for a while
```java
 				final IabResult result = new IabResult(
 				         responseCode == RESULT_NO_SIM ? RESULT_ERROR : responseCode 
 				      , (responseCode == RESULT_NO_SIM ? "No SIM. " : "") + "Failed to get buy intent.");
```
