I installed skype and had it running on my Samsung Galaxy s phone and configured it to ask me on each outgoing call to choose if to use the cellular line or skype out. It work fine on both Wifi and G3 connection. At some point somehow skype out became the default for outgoing calls and I couldn't figure out how to re-configure it to make calls via the cellular line. As result a decided to un-install skype. Afterward and since I have tried again and again to re-install skype, it downloads from market and at the end of the download tries to install and then I get a message that the installment failed due to "insufficient storage available." I have over 12giga free space on SD an 2gig on the internal phone memory. After not succeeding to install skype I check installing other apps and have no problem. Any ideas on how to reinstall skype? Thanks.
