I thought the big firmware update at the time the Sony bookstore closed was supposed to enable buying books from the Kobo store directly on the T-series readers? I haven't tried it myself.
I haven't shopped at Kobo, for various reasons, but I do use my PC to buy epub books from other bookstores (such as Google Play) and I use the Sony Reader for PC software to transfer the books from my PC to my PRS-T1.
I don't know if the Sony software is still available for download in Trocchietto's country. The last time I checked the US Sony support website, both software and firmware updates were still available for download.
