Thank you all for your replies. So is GSM power down and up equal to a reset and would do the thing? Related question - does anyone know an external charger for the 2nd Freerunner battery? Is it a good idea to use one of this cheap 5€ Nokia chargers, that are capable of charging a mobile and battery at the same time?
