Climbed the http://www.drachenwand-klettersteig.at/ with Rudy. Nice, not too hard, only the way down was very muddy and slippery.
See my photos; and also see Rudy's photos.

My Nokia 3500 phone had a broken, dark screen and was totally inoperable. Ordered a replacement screen on ebay (ave_store in Hong Kong) for US$ 10 (free shipping!)...
Following the disassembly guide, I managed to install the new screen within 20 minutes.
Unfortunately, opening the casing cleared the phone's memory and all the address book.

The phone only supports one or three SIP provider (depends on whether the SIM card is inserted) but new providers can be added by sending provisioning XML files. I created one for sipcall.at.
A sample XML file can be downloaded from Nokia, together with the Nokia Series 40 VoIP v81 Configuration Tutorial document which describes the relevant tags. After some experiments, I found that
stun.gmx.net should be added to make the phone accept call behind a firewall/NAT router.

The XML document needs to be converted into a binary representation via xml2wbxml: xml2wbxml -o sipcall.prov sipcall.xml and sent to the phone via bluetooth.
