File this strictly under bug-fixing, but there's a brand spanking new version of the Nokia Store client for modern Symbian phones available over at Nokia Beta Labs today. I'd noticed a number of installation issues recently and I'm hoping that these two will be a thing of the past. Upgrading is highly recommended.

The new version is 3.30.012 and replaces v3.22, also in beta. The quoted changelog is:

• Fixed: sign-in may fail after opening the client for more than 4 hours
• Fixed: on the old S^3 release, both the QML client and cWRT client can be launched by clicking the store icon
• Fixed: some translation issues

But I suspect there are other bug fixes implemented too. There's a full download with all the Qt 4.7.4 libraries included or you can grab the smaller download with just the new client.
